Close the app and then re-launch it. I experienced this issue and doing that fixed it.
I was on approach and the airport wouldn’t load, so once I closed the app, it still didn’t work!
Try cleaning cache next time, that usually fix’s it.
If that doesn’t work, change your 3D object density. That forces the objects to reload and they should be there. Also, what aircraft and graphic settings were you using? The pink in the first photo seems odd
